Because we'll have to get young and suck eventually.
I'm not convinced that the Celtics have to go through a "young and suck" phase between the current and the next championship windows.
The only way I could see that being the case is if Rondo turns into a superstar (i.e. legitimate top 4-5 MVP candidate) when he gets back from his injury.
We aren't building a contender post-Pierce/KG without a superstar, and we aren't getting one in free agency. So it's Rondo, tank for the lottery, or acquire various young assets over the course of a few years and make some trades.
Personally, I view the latter of the three options as the most likely one. But it means we have to get young and suck for a few years (at least).
I'm thinking it's going to be a combination of one and three.
That's fine, but it still requires us to get bad enough to be a borderline lottery team for a few seasons.
Could you explain why that's the case?
It's the most probable, given the current information. Right now it looks like Danny is going to trust his drafting record, and build assets around Rondo, with the team maturing around him, or trading for the pieces. Right now our long term pieces are Sully, Bradley, and spare parts. Possibly Green elevates himself to piece or asset, but his contract is pretty heavy bidness at the moment.
Lee and Bass are spare parts for a contender, nut unlikely building parts for a franchise on the mend, unless they're part of a package of the future assets we have, including our draft picks.
So to me the path is one of two ways; trade our current assets for future assets (Pierce/Garnett being the more prominent, including Lee, Bass and Green), trade our future assets for current assets, or stand pat.
If we're standing pat, you let Pierce and Garnett play, and hold on to the future assets (notably the 2014 puck and beyond) , and pray we draft well.
